What Is Rust?
What Is Rust?
Rust is a multi-paradigm, general-purpose programming language.
Rust emphasizes performance, type safety, and concurrency.
Rust enforces memory safety - that is, that all references point to valid memory - without requiring the use of a garbage collector or reference counting present in other memory-safe languages.
What Is Rust?
- Performance: no runtime and no garbage collector
- Reliability: rich type system and ownership model, memory-safety, thread-safety
- Productivity: comprehensive documentation, useful error messages, and lots of tooling
